in which material used in utility boiler
First, the concept of "soot blowing", the long-run gas in which material used in utility boiler, heating surface fouling and coking occur, so that the heat transfer deterioration; backpass respect, since the long-term accumulation of combustible material, is likely to occur reburning fuel incidents, hence the need for sootblowing work heating surface in the boiler after running for some time, in order to clean the boiler heating surfaces. Second, how to complete the "soot blowing" 1, using a short sootblower lance tube furnace for heating water wall surface sootblowing. 2, with a long flue soot-blowing lance tube, a superheater heating surface sootblowing reheater, economizer, air preheater and the like. Third, the "soot blowing" effect on the safe operation of the boiler to gas boiler soot blowers can cause negative pressure boilers, steam temperature, steam pressure, load, fluctuations in the water level, but also bring to the boiler soot blowing influence of different heating surface They are not the same, to deal with these parameters in the process of strengthening the soot-blowing view. On the impact of boiler soot blowing, in the following areas: 1, soot blowers for the stability of combustion have been affected, in the soot blowing process should strengthen the monitoring of combustion. 2, at low load operation and combustion instability, can not work sootblowing; simultaneously, so that the heating surface cleaning sootblowing, increased heat absorption, thus making the exhaust gas temperature is lowered. 3, since the sootblowing furnace pressure fluctuations result, a large negative pressure should be maintained in the furnace to prevent soot blowing to take pressure.
July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam in which material used in utility boiler contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.
DZL coal fired chain grate in which material used in utility boilers
How a 20 ton coal fired boiler working is a main question what clients caring about, here, I will talking about how a coal boiler working during production in briefly below:
Gas-fired in which material used in utility boiler medium test and cold cycle (1) the heat carrier used in the organic heat carrier furnace must be qualified and the operating temperature must be consistent with the heating conditions. The outlet temperature of boiler is at least 30 ℃ lower than that of heat carrier and 40 ℃ lower than that of heat carrier, otherwise it will decompose and fail in advance. (2) Oil loading: the injection pump of the qualified heat carrier for testing shall be injected into the boiler and, when the oil injection pump is injected into the system, the valves of all heating systems in the furnace body shall be re-checked and the sewage valve shall be opened one by one to remove the air until the oil flow is closed, Stop oil injection and start circulating pump when high expansion tank level meter appears. Cold oil circulation. (3) Cold oil cycle: the purpose of the cold oil cycle is to test whether there is resistance in the whole heating system and whether there is leakage in the valve of the equipment. Each pump must be wheeled to start cold oil circulating in the system for no less than 6 hours. (4) cleaning filter: some metal and impurity deposits in the system in the cold oil cycle are shut down with the cold oil in front of the oil pump, and the filter is thoroughly cleaned after the cold cycle is finished. When the organic heat carrier is used, the outlet temperature of the carrier is lower than the maximum operating temperature of 20 ℃ and 40 ℃ provided by the manufacture, and the adjustment index is the main one. Close to the outlet temperature, when the temperature difference between the inlet and outlet decreases, the combustion should be reduced accordingly. Combustion should be intensified when the return temperature is reduced. Never blindly raise the outlet temperature to increase the heat supply. When the outlet temperature overheating instrument alarm, the furnace should be shut down in time to clean.
